HOSE-COUPLING.

Specification of Letters Patent.

Patented Dec. 14, 1915,

Application filed August 5, 1914. Serial No. 855,203.

To all whom it may concern:

Be it known that I, Gnoucn P. FRANK, a citizen of the United States,residing at Roselle, in the county of Union and State of New Jersey,have invented a new and useful Hose-Coupling, of which the following isa specification.

The present invention appertains to a hose coupler, and aims to providea novel device for connecting a water or air hose to a hydrant, pipe,spigot, or the like, whereby the hose may move freely relative to thehydrant or other fixed water or air conductor to which the hose isconnected, and whereby the hose will not be liable to bend excessively.

Ordinarily, when a hose is connected to a hydrant, faucet, or otherfluid conduit, the hose in dropping to the ground, floor or otherunderlying surface, will have a short bend adjacent the hydrant, or thelike, which will in time cause the hose to break or rupture, especiallywhen the hose is moved about.

With the foregoing and other objections in mind, it is the object of thepresent invention to provide a simple and etiective device forconnecting the hose to a hydrant or other fixed fluid conduit, whichwill eliminate the usual short bend in the hose, and which will enablethe hose to move freely with respect to the hydrant, or the like,without interrupting the flow of the water or air, and without impairingthe present device.

\Vith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combinaticn andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made with in thescope of what is claimed without departing from the spirit of theinvention.

The invention has been illustrated in its preferred embodiment intheaccompanying drawing, wherein Figure 1 is a longitudinal section of theimproved hose coupler or connection, and Fig. 2 is a cross section takenon the line 2-2 of Fig. 1

In carrying out the present invention, there is provided an angular orcurved pipe 1, which has its arms arranged at an obtuse angle withrespect to one another, so that the formation of the pipe 1 will be suchas to enable the hose to be conveniently attached to and dropped from ahydrant or the like.

A hcse of any suitable character is adapted to be attached to cne end ofthe pipe or member 1, and to this end, a nipple 2 is provided upon whichthe end of the hose may be secured or clamped, and as illustrated, thenipple 2 .is provided with a threaded socket 3 at one end engaged overthe end of the corresponding arm of the pipe 1. It is to be understood,however, that various means may be provided for attaching the hose tothe pipe or member 1. The other end or arm of the pipe 1 is providedwith a counter-bore or sccket 4 which provides a stuffing box at thecor-responding end of the bore or passage 5 of the pipe 1, and at thebottom or inner end of the counter-bore or stufling box 4, the bore 5has a slightly enlarged porion 6, and the elbow has a beveled annularseat 7 between the bottom of the counterbore or stuffing box 4 and theenlarged portion 6;

An annular or gland nut 8 is threaded .into the mouth of thecounter-bore or stutting box 4, and a tubular member 9 is slidablethrough the nut 8, and is provided with a reduced end portion 10 whichfits snugly and slidably in the enlarged portion 6 of the bore 5, whilethe shoulder provided by the reduced end portion 10 is beveled, as at11, to snugly fit against the seat 7. I

A pair of annular compressible packing rings 12 embrace the tubularmember 9 within the stuffing box 4 and snugly engage the interior wallsof the stufiing bcx 4, and flat rings 13 are disposed slidably upon thetubular member 9 between the packing rings 12 to seat; thereagainst. Acoiled wire expansion spring 15 surrounds the tubular member 9 withinthe stufling box 4 and be tween the rings 13, to separate the said rings13 and to cause them to forcibly seat against the packing rings 12 forcompressing the same. .A retaining ring 15 is secured upon the tubularmember 9 adjacent the reduced end :10 thereof and is spaced from thebottom ofthe stufling box, for holding the parts 12, '13 and 14 upon thetubular member, it being noted that the expansive tendency of the spring14 will seat the respective packing rings 12 against "the :gland nut 8and ring 15, whereby the packing rings 12 will be compressedlongitudinally and expanded laterally to snugly and tightly engage thetubular member 9 and the walls of the stuffing box 4: to preventleakage. l urthermore,

the ring or retaining member 15 being secured upon the inner end. of thetubular member 9, will prevent the tubular member 9 from beingwithdrawn, although the spring 14 will enable the pipe 1 and tubularmember 9 to separate slightly if there is a tendency to pull them apart.

The tubular member 9 is adapted to be attached to a hydrant, supplypipe, or other water, air or other fluid conduit, and to this end, asocket nut 16 is mounted rotatably upon the protruding end portion ofthe tubular member 9, and the said end of the member 9 is provided withan outturned flange 17 within the socket nut 16. The socket nut 16 isadapted to be threaded onto 7 the nozzle 18 of the hydrant or other conduit, and a gasket 19 is preferably disposed within the socket nut 16 tobe compressed between the flange or lip 17 and the nozzle 18 when themember 9 is attached to the nozzle or member 18.

In assembling the present device, supposing all of the parts to beseparated, the socket nut 16 is first slid upon the tubular member 9,and the gland nut 8, packing rings 12, bearing springs 13 and the spring14 are in proper turn slid upon the tubular member 9. Finally, theretaining ring 15 is secured upon the tubular member 9 to hold the otherparts upon the tubular member. The tubular member is then inserted intothe 'stuiiing box a with the packing rings 1:2 and accompanying partsand the gland nut 8 is then threaded into the mouth of the stufiing boXl. The reduced end 10 of the member 9 will then enter the enlargedportion 6 of the bore 5, which will enable the tubular member 9 and pipe1 to move apart slightly, without withdrawing the reduced end portion 10of the member 9 completely from the bore 5. The end portion 10 of themember 9 fitting telescopically into the bore 5 will serve as a primarymeans for preventing leakage. The tubular member 9 may then be attachedto the nozzle or outlet 18 of a hydrant, or other conduit, through themedium of the socket nut 16, and the hose may be readily attached to thepipe 1, through the medium of the nipple or attaching member The arms ofthe pipe 1 being arranged angular-1y, will enable the hose to drop fromthe hydrant, or its equivalent, without the existence of the usual bendin the hose adjacent the hydrant, and furthermore, the pipe or member 1may swingupon the tubular member 9, to permit the hose to be drawn aboutwithout interference or without the liability of breaking or rupturingthe same. The present device therefore serves the two fold function, ofeliminating the bend in the hose asusual, and for enabling the hose tomove readily with respect to the hydrant or other object to which thehose is attached. ,a I

As above intimated, the spring 1 1 being disposed between the gland 8through which the member 9 is slidable, and the retaining ring 15 whichis secured upon the member 9, will hold the parts 1 and 9 together,although the spring Will enable the said parts to separate slightly whenthe hose is subject to strain in moving the same about. The spring 14will also compress thepacking rings 12 so that they will tightly engagethe tubular member 9 and the walls of the stuffing box at, to preventleakage.

In view of the foregoing, taken in connection with the drawing, theadvantages and capabilities of the present device will no doubt beobvious to those versed in the art,

Without further comment being deemed necessary, it being understood thatthe present device may be constructed in various sizes, according to itsvarious uses, and may be altered in its details within the scope of theappended claim, without departing from the spirit of the invention.

Having thus described the invention, what is claimed as new is A couplerembodying an elbow having a counter-bore at one end, the bore of theelbow having a slightly enlarged portion at the bottom of thecounter-bore, the elbow having a beveled annular seat between the saidenlarged portion of the bore and the bottom of the counter-bore, a glandengage-ct into the mouth of the counter-bore, a tubular member slidablethrough the gland and having a reduced end fitting slidably andmcounter-bore, packing rings between and seating against the gland andring, and an expansion spring disposed between the packing rings. r

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
